U.S. Sen. Kelly Ayotte gestures during a press conference at the American Embassy in Kabul, Afghanistan, Saturday, March 22, 2014. Ayotte stressed out during her brief visit to Afghanistan that no American forces would remain in Afghanistan without a bilateral security agreement, but she also said Obama shouldn’t wait for that to give an idea of what the U.S. presence would look like after the NATO-led combat mission ends at the end of this year.
